For the 28 days of Black History Month, the New York Times' film critics have selected 28 films centered on African Americans' experiences in 20th century USA. Beginning with "Within Our Gates" (1920), the list is in chronological order and includes some controversial, powerful and problematic issues. (For example, "Shadows" (1959) is about three black siblings, but two of the actors were white.) There's plenty of comedy too, thanks to "House Party," "Stir Crazy" and more. See the full list at the Times.
